ABSTRACT Large-pore mesoporous silica particles were synthesized through a solvent evaporation process using hydrophobic fumed silica
particles and tetraethyl orthosilicate (TEOS) as silica sources. The solvent evaporation of an ethanol solution of fumed silica
particles, TEOS, HCl and triblock copolymer (F127) resulted in mesoporous silica particles with pores with sizes of about
7nm. In addition, the interplanar spacing of the mesoporous silica particles can be controlled by changing the solvent evaporation
temperatures.
